Allow users to choose their preferred dose for alerting.

Most vaccines need two doses for being fully vaccinated against Covid19. The CoWIN API returns capacity for both dose1 and dose2.

1. Add topology to convert user->[pincodes] to pincode->[users]
2. Create producer that sends updated pincodes to updated-pincodes topic.
3. Add topology to combine updated pincodes KStream to pincode->[users] KTable
4. Add consumer to send notifications.
5. Persist Vaccine Centers in DB only when relevant changes are detected.

Sessions before "today" are not relevant and can be removed from the DB. Add a job to delete these sessions and conserve disk space.

The EC2 Graviton ARM based VMs are 40% cheaper than x86_64 VMs with same specs (T4g vs T3).

Allow users to set their age preference for alerts.

1. 18-44
2. 45+
3. Both

Some districts like Mumbai, Pune, Delhi, Bangalore etc are under many eyes and the open slots are filled within minutes. If the slots get filled within 5 minutes (current bot checking interval), the slots will be missed.

These districts should be checked more frequently (every 1 min?) to have less chances of missing slots.

In districts with less frequency of slots booking, users often receive notifications that is same as the previous notification (every 5 mins) with no change in slots. To avoid spamming the user all the time it would be better to check previous update and only send new update if it is different.

Allow users to choose their preferred Vaccine for alerting.

1. Covishield
2. Covaxin
3. ??

It should be easy to extend this list in future.
